LEVER-GUIDE.

Specification of Letters Patent.

Patented Mar. 18, 1913.

Application filed December 29, 1911. Serial No. 668,569.

b all whom it may concern:

Be it known that I, CHARLES H. IVILLIAMs, Jr., a citizen of the United States, residing at Chicago, State of Illinois, have invented a certain new and useful Improvement in Lever-Guides, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a side elevational view of my improved lever guide. Fig. 2 is a top plan view of the same. Fig. 3 is a top plan view of a modified form. Fig. 4 is a sectional view on line 44 of Fig. 3. Fig. 5 is a top plan view of another modified form. Fig. 6 is a side elevational view of the same. Fig. 7 is a top plan view of another modified form. Fig. 8 is a sectional view through the same.

This invention relates to a new and useful improvement in lever guides for car structures, the object being to mount the guide in such a Way as to compensate for movement of the bolster relative to the car truck.

In the well known type of Barber trucks, the bolster is provided with rollers under each end which permit a lateral movement of the bolster in the truck when the car is rounding a curve. The brake beams are ordinarily hung from the truck frame and connected to the truck bolster through the lever in the beam strut and the dead lever stop. The Barber truck, and certain types of swing motion bolsters, where the bolsters are suspended from stirrups or hangers, tend to strain the struts and break them. This condition has been met in some instances by using a curved hanger with lost motion at the hanger bracket fastening, which allows outward swinging motion of the beam, but this has not proven entirely satisfactory.

My present design provides means which compensates for the swinging of the bolsters without injury to the beam or other parts.

In the drawings, 1 indicates a portion of the side wall of a bolster and 2, a bracket lug secured thereto through perforated ears of which passes a pin 3. On this pin is slidingly mounted a bearing block 4: for the dead lever guide 5 which is pivotally connected thereto, and on each side of said bearing block are arranged springs 6 which permit said bearing block to be removed longitudinally the pin and thereafter to be restored to its central position by said springs.

In Figs. 3 and 4 I have shown the bearing block provided with an eye a which is slidingly mounted on a supporting rod 2 designed to be fastened to the truck bolster. The opening in this eye is of such size as to permit free movement of the bearing block, no springs being employed to restore the bearing block to its central position.

In Figs. 5 and 6, I have shown the bearing block t provided with a head at its inner end which is designed to slide within a T-shaped groove in a supporting bracket 2".

In Figs. 7 and S, I have shown the bearing block as having an enlarged cylindrical inner end 2 which is received in the bore of a supporting lug 2 vVhat I claim is:

1. The combination of a bolster and bearing block having a lever guide mounted thereon and capable of movement relative to said bolster.

2. The combination of a bolster and a lever guide movably mounted thereon and being movable in a direction lengthwise said bolster.

3. The combination of a bolster and a lever guide pivotally mounted thereon and capable of movement relatix e to said bolster in a direction at an angle to its pivotal movement.

4. The combination with a bolster, of a lever guide mounted thereon and capable of movement relative thereto and means for centering said lever guide.

5. The combination with a bolster, of a supporting member attached thereto and a lever guide pivotally mounted in said supporting member and having movement lengthwise thereof.

6. The combination with a bolster, of a bearing block pivotally mounted thereon and also having a movement at an angle to the direction of its pivotal movement, and a lever guide connected to said bearing block.

7. The combination of a bolster, and a brake lever bearing block pivotally and slidingly mounted on the side thereof.

8. The combination with a bolster, of a bearing block movably mounted thereon, and means for centering said bearing block.

9. The combination of a bolster and a brake lever bearing block slidingly mounted my signature in the presence of two witthereon. nesses, this 23rd day of December, 1911.

10. The combination of a bolster a brake lever bearing block slidingly lnounted CHARLES VILLIAMS 5 thereon and means for centering said bear- Witnesses:
